To guarantee that all these nutrients are gifts in the daily diet, FDA (Food and Drug Administration – agency of the government of U.S.A. that controls the production and commercialization of remedies and foods), praises the consumption of the following daily portions of foods that composes the Alimentary Pyramid: Group of Breads, Cereals, Rice and Masses: 6 – 11 portions per day; Grupo of Vegetables: 3? 5 portions per day; Grupo of the Fruits: 2? 4 portions per day; Grupo of the Laticnios: 2? 3 portions per day; Grupo of the Meats, Ovos and Leguminosas: 2? 3 portions per day; Grupo of Fats, Oils and Sugars: sporadical use. The alimentary pyramid separates energy, regulating, construction foods in and energy extras. These foods must be consumed in sequence decreasing, that is, must consume in bigger amount the energy ones, followed of the regulators, the constructors and finally the energy extras, of limited consumption. We can then observe in the base of the pyramid, the rich foods in carboidratos (energy), followed for the ingestion of fruits and main vegetables sources of vitamins and minerals (regulating), above we have foods protein sources (constructors), and finally the fats and the sugars (energy extras), that they must have a sufficiently restricted ingestion. 5.O value of the Diet the beneficial effect of the consumption of a diet with low glicmico index would consist in the long run of the reduction of the peak after-prandial of insulina and glucose, promoting lesser pancretica overload, whose bankruptcy could direct be originated by a toxic effect caused for the hiperglicemia. Moreover, it is suggested that the adverse effect of a diet with raised glicmico index would be related to the increment in the concentration after-prandial delayed of acid greasy free, producing bigger resistance to the insulina. This mechanism would be unchained by the hipersecreo of contraregulatrios hormones, such as cortisol, glucagon and hormone of the growth, in result of the reacional hipoglicemia promoted by a diet of raised glicmico index.
